Degenerate two-photon indirect absorption in silicon is an important
limiting effect on the use of silicon structures for all-optical
information processing at telecommunication wavelengths. Optical
injection of spins in silicon is potentially important for
spintronics
applications. We theoretically investigate one- and two-photon
indirect absorption in silicon, using a pseudopotential
description of
energy band and the adiabatic bond charge model to describe phonon
dispersion and polarization. Spin injection is calculated as well. We
compare our results with experiments.
